Donny: Thank you for sharing your experience with me, but you got me wrong:
lucid (Kernel 2.6.32) doesn't support the *powermanagment for Radeon GPUs* very well (if you're using KMS).
My own T60 with Mobile Radeon X1400 takes about 18 watts with an installed lucid but only 12 watts with maverick rc live or this well known "other OS" ;-), (all with lowest brightness to be comparable)
With maverick on the other hand I'll have my 12 watts but slow WiFi.
